CP (Cellular Phone) is currently one of the most attractive technologies and RT (Robot Technology) is also considered as one of the most promising next generation technology. We present a new technological concept named RCP (Robotic Cellular Phone), which combines RT and CP. RCP consists of 3 sub-modules, $RCP^{Mobility}$, $RCP^{Interaction}$, and $RCP^{Integration}$. $RCP^{Interaction}$ is the main focus of this paper. It is an interactive emotion system which provides CP with multi-emotional signal receiving functionalities. $RCP^{Interaction}$ is linked with communication functions of CP in order to interface between CP and user through a variety of emotional models. It is divided into a tactile, an olfactory and a visual mode. The tactile signal receiving module is designed by patterns and beat frequencies which are made by mechanical-vibration conversion of the musical melody, rhythm and harmony. The olfactory signal receiving module is designed by switching control of perfume-injection nozzles which are able to give the signal receiving to the CP-called user through a special kind of smell according to the CP-calling user. The visual signal receiving module is made by motion control of DC-motored wheel-based system which can inform the CP-called user of the signal receiving through a desired motion according to the CP-calling user. In this paper, a prototype system is developed for multi-emotional signal receiving modes of CP. We describe an overall structure of the system and provide experimental results of the functional modules.

The purpose of this study is to develop a photomontage expression in order to express a characteristic personality and creativity of artists of effectively in fashion illustration. The results of this study were as follows : 1) Because of a fashion and a human body were the major subjects in fashion illustration, human body transformation and composition between a human body and heterogeneous objects by photomontage appeared with a lot of works. 2) Photomontage appeared with a parody in a truth recurrence differ from a visual art, a parody seemed to be a humor with recurrence image of the original and it appeared with the general public image and it is effective in message delivery. 3) It was a stopped screen. but photomontage was expressed through overlapping and reiteration was characteristic, and it appeared with movement. a direction, a speed and rhythm effectively. 4) One screen of general chapter was only to express limited meaning, but after screen of a lot of chapter, it was able to express that was borrowed and reconstructive with a lot of contents or different contents are more than before. 5) It is changed, and composited images have a multiple point of time, and it extend a space-time limit, visual limit and an expression enabled a multidimensional space-time. Moreover, photomontage neglects unique sincerity and fact of a photo by development and utilization of computer graphic. and it can get a screen effect to spread in the virtual world as abstraction and hyper-reality. Therefore, if various photomontage expression apply to fashion illustration works, it can overcome a limit of a visual expression. and it is able to become an important way for expanding a filed of expression and enhancement of a practical function gradually in fashion illustration

Natural forms could be ultimate visual expression power that affects on the industrial design. The rule of power in nature as nature formal characteristics have a direct influence and can be also applied to productional and artificial form. All organic forms and structures in nature have unique form and shape to be self controlled and good in order. Such an order in nature comes from regular and ratio principles which has aesthetical order by mathematics. The specialty of beauty in nature can be revealed not only visual form but also the ratio, balance and rhythm of structural principles. As we examine the aesthetic source, embodied some object can be developed into basic principles. Furthermore, through this study we can find out that the form theory in nature forms share the quality attribute with geometrical form to be shown in industrial product design. In this context, this study aims to make dear visual quality of organic form and structure that is immanent in nature about a form as formative principles of industrial product design, the significancy of this study is to prove the application into functional and structural form of product design.

The purposes of this research are firstly to define the characteristics of movement on the costume, secondly to demonstrate that fine art, expecially in relation to kinetic art, has become a good motif in modern costume de-sign, and thirdly to examin the characteristics of movement as shown in modern costume de-sign. For this study, we selected and analyzed some costume designs among those introduced in fashion magazines, which are Collections, Fashion-Preview, Fashion Show, Collezioni, and L'Officiel that have been issued since 1988. As this research is carried out only through the analysis of pictures, it is not ac-companied by a study on material itself. The result of this study is that the ex-pression of movement on modern fashion can be shown in two ways, one is the inclusive and subordinate movement expressed on the cloth-ing according to the motion of body when they are worn, and the other is the movement caused by the very designs of clothing. And the latter can be also divided in two ways, the illusionistic movement and the actual move-ment. The expression of actual movement is made through the emphasis of direction, rhythm, and dimension of the costume. And the illusionistic movement is expressed by the de-sign to which the textile pattern or reflection of light is applied so that the movement is larger than the actual movement. A sense of direction expressed on the cos-tume by the actual movement creates a light rhythm and adds interest to the costume. This reflects a part of psychology of modern men who are not accustomed to the statics. In the rapidly changing society of information our modern men seek after movement even in the statics. It is also true in the clothing and they seem to get a psychological rest through the immediated visual change as shown in fashion design. The simple and cheerful rhythm expressed by the illusionistic movement on the costume is attempted in order to overcome the static tediousness caused by simple design. These elements of movement cause the en-largement of visible range and create another enlarged shape other than the real one, so that they come to remove the dullness and monot-ony in costume design and provoke interest in costume, as if kinetic art reveals the various aspects that transcend the closed area of fine art upon the motif of 'movement'. finally, as this paper deals with the ex-pression of movement as shown in the costume design which prevailed after 1988, it is desir-able hereafter to study more about the fashion since 1950 when kinetic art began in earnest, along with the comparative study on the ex-pression of movement in our Korean designer's and foreign designer's works.

According to a recent KOFICE survey, K-Pop's popularity factor is divided into visual and auditory elements, and the importance of hearing elements is found. Among the various types of singers, idol groups led K-Pop and Black Pink, which topped the list of favorite K-Pop singers in 2018, was selected as the study target. In addition, Twice's music, which is similar to Black Pink's period of activity, has been set as a comparative research scope. The common features in the music of the two groups are the chorus and rhythm structure implemented around melody and Harmony rhythm, and the frequency of use of Major and Minor is greatly different. Through this method and modal interchange, K-Pop from 2016 to 2018 is analyzed. Research shows that first, more than one mode is used as a main melody. When more than one mode is used, different lines in the same line will vary depending on the functional form of the song. Second, the rhythm of the melody expressed with vocals and instruments is repeated based on a two-bar pattern. Finally, when using less chord and slowly expressing the igneous rhythms, there is a way to omit or modify the third notes that determine chord characteristics. Through this study, we can see that the usage patterns of the mode and modal interchange are divided according to the major and minor.

This study measured and analyzed musical sense objectively, and visualized it to express visual effects as if watching music with the eye. For the visualization of music, we examined the concept of synesthesia and the correlation between hearing and seeing, and reviewed theoretical grounds and a number of cases necessary in reproducing musical sense visually based on synesthetic expression. Furthermore, we studied the visual elements and associated colors of rhythm to prove that visual conception of music through various approaches enable a transitional approach to aesthetic exploration and interpretation. The conclusions drawn from this research are as follows. First, classic music selected for visualization had musical characteristics highly correlated with dress design. Second, basic formative elements suggested as materials of visualization in this study were suitable in their form for expressing the rhythmic sense of music and, because they started from the most basic form, they were effective in extracting design elements. Third, when the result of the questionnaire survey, which was focused on the visualization of the rhythmic sense of the five pieces of classic music, was analyzed from the aspect of sensibility ergonomics, design elements of each piece of music were obtained in an objective and scientific way. Fourth, it was confirmed that common concepts could be derived from intangible elements such as forms and sounds observed in the rhythmic sense of music obtained from the result of the questionnaire survey. Fifth, works were made based on the results of this study and, according to the result, musical images can express sense through dress design and obtain visual effects as if watching music with the eye. Dress desist through the visualization of music in this study was an attempt to suggest that the language of music can be expressed in dress design, a visual formative language, based on synesthetic expression. Through this attempt, we confirmed the infinity of music as motives of dress design and suggested a method of aesthetic expression demanded in contemporary society that is pursuing aesthetic values.

Purpose: This study compared the effects of Static stretching and Mulligan's Two-leg rotation about the Hamstring flexibility, Hip range of motion, and pain. Methods: The subjects were allocated randomly into two groups: Static stretching group (n=13) and Mulligan's two leg rotation group (n=14). The study was designed with stretching protocols for four minutes and thirty seconds per day five times a week for three weeks in total. Measurements, including the Sit and reach test, Active/Passive Straight leg raise, and Visual analogue scale, were conducted before and after the intervention. The data were analyzed using a paired t-test and independent t-test. Results: The flexibility of the two leg rotation group was higher than the static stretching group after the intervention. The post-sit and reach test value of the two leg rotation group was significantly higher than the pre-sit and reach test value of the static stretching group. In addition, the variance of the sit and reach test of the two leg rotation group was significantly higher than that of the static stretching group. Conclusion: These results showed that two leg rotation techniques have a positive effect on the changes in the sit and reach test and active straight leg raise test. Two leg rotation techniques can be recommended as a self-stretching and easier way to stabilize the lumbopelvic rhythm, reduce the stiffness of the muscle and relieve pain. This is effective in preventing muscle damage, enabling muscle relaxation and reducing the risk of injury to the spine during daily lives and in sports activities.
